feat!: GUI-only approval, repo slug display, version 0.2.0

[lklimek]

Summary

• Show repo slug in approval dialog — displays owner/repo (e.g. lklimek/ghsudo) instead of just the org name, when detectable from -R/--repo args or git origin remote
• Remove --no-gui / terminal fallback — terminal prompts are trivially auto-approvable by AI agents, defeating ghsudo's purpose. A graphical display is now required (exit code 3 if unavailable)
• Single version source — version defined only in pyproject.toml, read at runtime via importlib.metadata
• Add CLAUDE.md — developer guide with release process
• README updates — Linux-only testing note, ssh -X tip, updated exit code docs
• 28 new tests for repo slug detection, org detection, and approval message formatting

Breaking changes

• --no-gui flag removed
• ghsudo now exits with code 3 if no graphical display is available (no terminal fallback)

Test plan

• All 28 tests pass (pytest tests/ -v)
• Verified GUI dialog shows "Repository: lklimek/ghsudo" via X11 forwarding
• Verified exit code 3 when no display available
• importlib.metadata.version() reads 0.2.0 correctly

Pull request overview

This PR updates ghsudo to require GUI-based approvals (removing terminal fallback), improves context shown in approval dialogs by detecting and displaying the full owner/repo slug, and consolidates versioning to a single source in pyproject.toml.

Changes:

• Add repo slug detection (from -R/--repo args or git origin) and display it in approval prompts.
• Remove terminal approval fallback and require a graphical display (exit code 3 if unavailable).
• Move version to pyproject.toml only and read it at runtime via importlib.metadata; add tests and docs updates.

• pytest is imported but never used in this test module. Removing the unused import will avoid lint noise (and keeps the tests module minimal).

• The comment on this branch says rc is None means "not installed or timed out", but _run_gui now returns 1 on timeout (and None only when the tool is missing). Update the comment to avoid misleading future changes/debugging.

    if rc is None:
        return None  # not installed or timed out
    return rc == 0
